After the hairdresser Jenny had 27 centimeters cut off her hair how many decimeters of hair did jenny have cut off

Answers

Answer 1

Answer:

  2.7 dm

Step-by-step explanation:

You want to know the number of decimeters in 27 centimeters.

SI Prefixes

The SI prefix "deci-" means 1/10.

The SI prefix "centi-" means 1/100.

This tells you that 10 cm = 1 dm.

  27 cm = (27 cm) × (1 dm)/(10 cm) = 2.7 dm

Jenny had 2.7 dm of hair cut off.

In a tournament team A won 7 less games than Team B, and Team B won exactly three times as many games as team C. If If Team C won g games, how many games did Team A win?

Answers

Team A won 3g - 7 games, where g is the number of games won by Team C. To determine the number of games Team A won, multiply the number of games Team C won by 3 and subtract 7.

Let's denote Team C's number of wins as g. According to the information provided, Team B won three times as many games as Team C, which can be expressed as 3g. It is also stated that Team A won 7 fewer games than Team B. So, if Team B won 3g games, then Team A won 3g - 7 games.

To find the number of games Team A won, simply multiply the number of games Team C won by 3 and subtract 7 from that total. This can be represented by the algebraic expression A = 3g - 7, where A represents the number of games won by Team A and g represents the number of games won by Team C.

Tripp and Rico are two dogs. Tripp weighs exactly 35 pounds more than Rico. Together, they weigh exactly 49 pounds. How much does each dog weigh? Please use Two-step equations!!!! plz, help!

Answers

Call the weights of the two dogs [tex]t[/tex] and [tex]r[/tex].

We know that Tripp weights 35lbs more than Rico, or:
[tex]t=r+35[/tex]

We also know that the total weight of both dogs is 49lbs.:
[tex]t+r=49[/tex]

Now, by substitution:
[tex](r+35)+r=49[/tex]
[tex]2r+35=49[/tex]
[tex]2r+35-35=49-35[/tex]
[tex]2r=14[/tex]
[tex]r=\frac{14}{2}[/tex]
[tex]r=7[/tex]
Rico weighs 7lbs.

Then:
[tex]t=r+35[/tex]
[tex]t=7+35[/tex]
[tex]t=42[/tex]
Tripp weighs 42lbs.

To check our work:
[tex]t+r=49[/tex]
[tex]42+7=49[/tex]
[tex]49=49[/tex]  CHECK!

Using a system of equations, it is found that Tripp weighs 42 pounds and Rico weighs 7 pounds.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are given as follows:

Variable x: Tripp's weight.Variable y: Rico's weight.

Tripp weighs exactly 35 pounds more than Rico, hence:

x = 35 + y.

Together, they weigh exactly 49 pounds, hence:

x + y = 49

35 + y + y = 49

2y = 14 -> y = 7

x = 35 + y -> x = 42

Hence, Tripp weighs 42 pounds and Rico weighs 7 pounds.

Arthur took out a 20 year loan for $60,000 at an APR of 4.4% compounded monthly. Approximately how munch would save if he paid it off 3 years early Apex A. $4516.32,B. $1129.08,C. $376.36,D.$877.96

Answers

Answer:

  D.  $877.96

Step-by-step explanation:

You want the amount saved if a 20 year loan of $60,000 at 4.4% is paid off 3 years early.

Payment

The monthly payment on the loan can be found from ...

  [tex]A=\dfrac{Pr}{12(1-(1+r/12)^{-12t})}[/tex]

where P is the loan amount at rate r for t years.

For the 20 year loan of $60,000 at 4.4%, the payment is calculated as ...

  [tex]A=\dfrac{60000(.044)}{12(1-(1+0.044/12)^{-12\cdot20})}=\dfrac{220}{0.584549}=376.3585[/tex]

Balance due

After 204 payments on the loan, the remaining balance due is ...

  [tex]A=P\left(1-\dfrac{(1+r/12)^n-1}{(1+r/12)^{12t}-1}\right)\\\\\\A=60000\left(1-\dfrac{1.0036667^{204}-1}{1.0036667^{240}-1}\right)=12671.04[/tex]

Savings

The remaining 36 payments on the loan come to about ...

  36 × 376.3585 ≈ 13548.91

So, the savings from early payoff is about ...

  13548.91 -12671.04 ≈ 877.86

Choice D, $877.96, is the best match for this value.

__

Additional comment

The actual savings will depend on the details of rounding of intermediate values in the calculation, and on the timing of the early payment. If the loan is amortized over 17 years, so more is paid each month, the savings can be more than $5000.

Here, we have calculated the savings on the assumption that payment number 204 includes the payoff amount.

Using the loan formula, monthly payments are $458.14. Remaining balance after 17 years is approximately $58,214.19. The savings would be approximately $1,785.81. The closest option to this calculation is  C. $376.36

To calculate the amount saved by paying off the loan 3 years early, we need to find out the remaining balance of the loan after 17 years (20 years - 3 years). Then, we compare the remaining balance to the original balance to find the savings.

Let's break down the steps:

1. Find the monthly interest rate (r):

[tex]\[ r = \frac{4.4\%}{12} = \frac{0.044}{12} \][/tex]

2. Calculate the total number of payments (n):

[tex]\[ n = 20 \times 12 = 240 \text{ months} \][/tex]

3. Use the formula for the monthly payment (PMT) of a loan:

[tex]\[ PMT = \frac{P \cdot r \cdot (1 + r)^n}{(1 + r)^n - 1} \][/tex]

where:

P = principal amount (loan amount)

r = monthly interest rate

n = total number of payments

We'll use PMT to find out the monthly payment Arthur has to make.

4. Use the monthly payment (PMT) to find the remaining balance after 17 years (204 months).

5. Finally, calculate the savings by comparing the remaining balance to the original loan amount.

Let's do the calculations:

1. Monthly interest rate:

[tex]\[ r = \frac{0.044}{12} = 0.00367 \][/tex]

2. Total number of payments:

[tex]\[ n = 20 \times 12 = 240 \text{ months} \][/tex]

3. Monthly payment (PMT):

[tex]\[ PMT = \frac{60000 \cdot 0.00367 \cdot (1 + 0.00367)^{240}}{(1 + 0.00367)^{240} - 1} \][/tex]

[tex]\[ PMT = \frac{60000 \cdot 0.00367 \cdot (1.00367)^{240}}{(1.00367)^{240} - 1} \][/tex]

[tex]\[ PMT = \frac{60000 \cdot 0.00367 \cdot 1.937}{1.937 - 1} \][/tex]

[tex]\[ PMT = \frac{429.33}{0.937} \][/tex]

[tex]\[ PMT= 458.14 \][/tex]

4. Remaining balance after 17 years (204 months):

[tex]\[ PV = \frac{PMT \cdot (1 - (1 + r)^{-n})}{r} \][/tex]

[tex]\[ PV = \frac{458.14 \cdot (1 - (1 + 0.00367)^{-204})}{0.00367} \][/tex]

[tex]\[ PV = \frac{458.14 \cdot (1 - 0.533)}{0.00367} \][/tex]

[tex]\[ PV = \frac{458.14 \cdot 0.467}{0.00367} \][/tex]

[tex]\[ PV = \frac{213.94}{0.00367} \][/tex]

[tex]\[ PV = 58214.19 \][/tex]

5. Savings:

Savings = 60000 - 58214.19

Savings ≈ 1785.81

So, Arthur would save approximately $1785.81 by paying off the loan 3 years early.

The closest option to this calculation is  C. $376.36

The gpa at the super university has a normal distribution with a mean 2.29 and standard deviation 1.29 to be an honors student at this university your GPA has to be in the top 20% what is the smallest gpa you need to have to be an honors student?

Answers

The smallest GPA needed to fall in the top 20% is [tex]g[/tex], where

[tex]\mathbb P(G\ge g)=0.20[/tex]

where [tex]G[/tex] is a random variable denoting GPA scores. Transform [tex]G[/tex] to the standard normal random variable [tex]Z[/tex] using

[tex]Z=\dfrac{G-\mu_G}{\sigma_G}\iff G=\mu_G+\sigma_GZ[/tex]

where [tex]\mu_G[/tex] and [tex]\sigma_G[/tex] are the mean and standard deviation of [tex]G[/tex], respectively. Now

[tex]\mathbb P(G\ge g)=\mathbb P\left(Z\ge\dfrac{g-2.29}{1.29}\right)=0.20[/tex]

Using the inverse CDF for the standard normal distribution, we find that the corresponding critical value is about 0.8416, which means

First step is to combine like terms. 

9 = 7x - 13x - 21 becomes 9 = - 6x - 21

Now add 21 to both sides to isolate our coefficient and variable. 

- 6x -21 + 21 = 9 + 21

The 21s on the left cancel out. 

- 6x = 30

Now divide both sides by - 6 to isolate the variable.

According to the geometric mean (leg) theorem, the length of the leg of a right-angled triangle is the geometric mean between its hypotenuse and the segment of the hypotenuse which is adjacent to that leg.

Mathematically, the geometric mean (leg) theorem can be modeled by the following formula;

Hypotenuse/leg = leg/part

where;

hypotenuse = 14 + 5 = 19

leg = m

part = 5

By applying geometric mean (leg) theorem, the length of the part (x) can be calculated as follows;

19/m = m/5

By cross-multiplying, we have the following:
